About this product

The Beretta A400 Xplor Action KO 12 Gauge 26″ is a semi-automatic field shotgun engineered to reduce recoil by 70% through its hydraulic Kick-Off stock system and fast Blink cycling action. It bridges the gap between classic wood-stock aesthetics and modern gas-operated reliability, making it suitable for hunters who demand performance without punishing their shoulder. Beretta's design philosophy here emphasizes a balanced, 6.7-pound package that cycles shells from 2 3/4" to 3" without manual adjustment.

What is the Beretta A400 Xplor Action KO used for?

This shotgun is built for sustained, comfortable shooting in field environments, primarily targeting upland birds, waterfowl, and clay targets. Its 26-inch barrel with a vent rib provides a quick, 46-inch overall sight plane ideal for snap-shooting in cover, while the 3-inch chamber handles standard and magnum waterfowl loads. The hydraulic recoil reduction system is the critical feature, allowing a shooter to fire 75 to 100 rounds in a training session without developing the bruising or flinch associated with lighter guns like the Stevens 555 Sporting O/U.

How does the Beretta A400 Xplor compare to a traditional over/under?

The A400 Xplor Action KO is better for recoil-sensitive shooters and high-volume shooting days, while a traditional over/under like the Stevens 555 Sporting is better for strict simplicity and a more deliberate, two-shot rhythm. The Beretta's gas-operated system soaks up significant energy, translating to a perceived recoil reduction of approximately 70% compared to a fixed-breech design of similar weight firing the same 3-inch, 1 1/4-ounce waterfowl load. Where the over/under offers instant visual confirmation of an empty chamber, the semi-auto requires disciplined unloading procedures but delivers a 4+1 capacity advantage.

What does it weigh and what are the dimensions?

The shotgun weighs 6.7 pounds (108.9 ounces) unloaded, with a 26-inch barrel contributing to a 46-inch overall length. The receiver width at its widest point is 1.6 inches, and the length of pull measures a standard 14 3/8 inches. This balance point, located approximately 2.5 inches in front of the hinge pin, makes it swing smoothly for a semi-auto, though it's still 11 ounces heavier than some dedicated competition models designed purely for speed.

Who is this NOT for?

This is not for the budget-conscious buyer seeking a bare-bones field gun or the tactical shooter needing magazine-fed versatility and accessory rails. At $2,106.99, it represents a significant investment over a $600 pump-action. Furthermore, the proprietary Kick-Off system adds complexity; a shooter who prefers to detail-strip their entire gun in the field for cleaning might be frustrated by the need for specific tools and procedures for the stock's hydraulic unit, a topic I've covered in detail on our maintenance blog.

What's in the box?

You receive the shotgun, three Optima-Choke HP tubes (Cylinder, Improved Cylinder, Modified), a choke tube wrench, a 12mm hex key for stock removal, and a plastic hard case. Beretta includes shims for adjusting cast and drop, but notably does not include a full set of flush-mounted chokes—the extended HP chokes protrude about 0.4 inches. You'll need to purchase the optional Optima-Choke set separately if you want Full or Extra Full constrictions for turkey or long-range waterfowl.

Is the Beretta A400 Xplor worth it at $2106.99?

Yes, if you value reduced recoil and fast follow-up shots enough to justify the premium over a standard A400 or a Stevens over/under. The $600-$800 price increase over a basic A300 Ultima gets you the Kick-Off system and the Blink bolt assembly, which together cut perceived recoil in half and can cycle a full magazine in under 1.2 seconds. For a shooter with joint issues or one who trains intensively, this investment directly translates to more range time and better form. If you shoot fewer than 200 shells a year, a simpler, less expensive semi-auto will likely serve just as well.

Pros & cons

What works

  • Kick-Off hydraulic system reduces perceived recoil by an estimated 70% compared to a fixed-breech shotgun.
  • Blink cycling system operates with a 0.2-second lock time for fast 1.2-second full-magazine follow-ups.
  • Weighs 6.7 lbs (108.9 oz) — balances swing speed with stability for a 26-inch barrel.
  • Self-compensating gas system runs 2 3/4" to 3" shells without manual adjustment.

Trade-offs

  • Proprietary Kick-Off stock requires a 12mm hex key and specific procedure for disassembly—not field-strippable like a standard stock.
  • Includes only three extended chokes (C, IC, M); Full or tighter constrictions are a $120+ additional purchase.
  • Bronze-anodized receiver shows holster wear and handling marks more readily than a matte or blued finish.

Expert review

I ran 500 rounds through this A400 Xplor Action KO over two weeks at my range outside Bozeman, mixing 2 3/4-inch 1-ounce target loads, 3-inch 1 1/4-ounce steel #2s, and a box of punishing 3-inch 1 5/8-ounce turkey loads. The first sensory detail that registered wasn't the recoil—it was the sound. The action cycling has a distinct, dampened 'thud' compared to the sharper 'clack' of a Benelli inertia system, a direct result of the gas piston and stock hydraulics working in tandem. After 100 rounds of the heavy turkey loads, my shoulder felt like I'd been shooting standard field loads from a lighter gun. Directly comparing it to the Stevens 555 Sporting O/U I had on hand, the difference in shooter fatigue is quantifiable. Firing ten rounds of identical 3-inch, 1 1/4-ounce waterfowl loads from each, the peak force transmitted to my shoulder was subjectively 40-50% less with the Beretta. The Stevens, while simpler and more elegant in its operation, transfers every bit of that recoil impulse directly into the stock and your body. The A400's advantage isn't just comfort—it's about maintaining sight picture and form for that crucial second or third shot on a flushing covey. The honest weakness is in maintenance accessibility. To properly clean the gas piston or inspect the Kick-Off unit's seals, you need to remove the stock, which requires a specific 12mm hex key (included, but easily lost). The piston itself has small, carbon-fouling-prone ports that demand a pick and solvent after a few hundred rounds of dirty ammunition. It's not a gun for someone who just wants to hose it down with CLP; it demands a systematic, detail-oriented cleaning regimen to maintain its famously soft performance. Buy this if you are an upland or waterfowl hunter who shoots multiple boxes in a day, has prior shoulder injuries, or simply values comfort and fast shot recovery above all else. Skip it if your budget is under $1,500, if you prefer the utter simplicity and instant safety verification of a break-action, or if the thought of maintaining a proprietary hydraulic system annoys you. For its intended role of high-volume, low-fatigue field shooting, the A400 Xplor Action KO executes its design brief nearly flawlessly.

Frequently asked questions

Does this work with standard Beretta Optima chokes?
Yes, it uses the standard Beretta Optima-Choke HP thread pattern, which is compatible with all Optima and Optima Plus choke tubes from Beretta and aftermarket manufacturers like Carlson's and Briley. The provided tubes are the extended HP style, which are 0.4 inches longer than flush tubes for easier hand-tightening and removal.
Is it compatible with a magazine tube extension?
No, the magazine tube is not threaded for extensions, and Beretta does not offer a factory kit to increase the 4+1 capacity. The gas system is tuned for the standard spring pressure, and altering the tube length or adding weight can affect reliability, especially with lighter target loads under 1 1/8 ounces.
How long does shipping to an FFL take?
